Description
FIELD OF THE INVENTION
[0001] The present invention relates to an antenna device with a
resonant pattern, and in particular to an antenna device with an
ion-implanted resonant pattern.
BACKGROUND OF THE INVENTION
[0002] It is well known that an antenna is the key element to
transmit/receive (transceive) microwaves in wireless technology
such as wireless communication and wireless data transfer, where
the antenna converts electrical currents generated by a transmitter
into microwaves and transmits the microwaves in free space. The
antenna also captures microwaves and converts them into electrical
currents, which are then processed by a receiver. As a result, the
characteristics of the antenna deeply affect that of the wireless
technology, and the antenna can be referred as the index to examine
the quality of the wireless technology.
[0003] Currently, antennas of conventional use are required with
specific dimensions, and only the antennas with the required
dimension optimize the feeding and transceiving of wireless
signals. Many of those skilled in the art, therefore, utilize a
resonant circuit to resonant with the antenna in order to magnify
the electrical current fed to and transceived by the antenna, so as
to reduce the noise and enhance the gain of the antenna to upgrade
the quality of the wireless technology.
[0004] Please refer to FIG. 1 that shows a conventional use of a
resonant circuit applied to the antenna. As shown in the figure, an
antenna 1 couples with a resonant circuit 2, which is composed of
an inductance 21 and a capacitor 22, in order to magnify the
electrical current fed to and transceived by the antenna 1. As the
antenna element 1 transceives the wireless signal of the
predetermined radiation frequency and generates an induction
voltage V1, the inductance 21 and the capacitor 22 each generates a
coupled induction voltage V2 and a capacitance therebetween. As a
consequence, the inductance 21 and the capacitor 22 form a
resonance with the antenna element.
[0005] Although some of the conventionally used electronic devices
with antennas in the market are accompanied with resonant circuits
to upgrade the quality of the transceiving of the wireless signals,
the resonant circuits are in fact individually manufactured and
then arranged in the electronic devices and electronically
connected to the antenna. Such manufacturing is not only
troublesome bust also increases costs.
SUMMARY OF THE INVENTION
[0006] A primary object of the present invention, therefore, is to
provide an antenna device with an ion-implanted resonant pattern,
which functions the same as a resonant circuit. Further objects of
the present invention are to provide a resonant pattern
co-structured with an electronic device and a resonant pattern
capable of resonating with an antenna.
[0007] To realize the above objects, the present invention installs
an antenna device having a substrate, an antenna element for
transceiving a wireless signal, an antenna signal feeding line for
feeding the wireless signal, and an ion-implanted resonant pattern,
which includes a first coupling pattern implanted in the substrate
by an Ion-implantation process and a second coupling pattern formed
at a position corresponding to the first coupling pattern with a
predetermined distance therebetween, formed at an adjacent position
with respect to the antenna element. As the antenna element
transceives the wireless signal of the predetermined radiation
frequency and generates an induction voltage, the first coupling
pattern and the second coupling pattern each generates a coupled
induction voltage and a capacitance therebetween, hence forming a
resonance with the antenna element.
[0008] In the preferred embodiment of the present invention, the
substrate is a casing of an electronic device, and the antenna
element is arranged on an inner surface of the casing. In addition,
the second coupling pattern is implanted in the casing of the
electronic device by the process of Ion-implantation as well.
[0009] In comparison with the conventional technologies, which the
resonant patterns are in fact individually manufactured and then
arranged on a base or an inner surface in the electronic devices,
the present invention implants an resonant pattern inside the
structure of an electronic device by applying the process of
Ion-implantation. Besides, the electronic device co-structured and
ion-implanted resonant pattern magnifies the electrical current fed
to and transceived by the antenna, as well as reduces the noise and
enhances the gain of the antenna to upgrade the quality of the
wireless technology. Further, the present invention can be adapted
into a wide range of electronic devices when used in different
fields of application.
[0010] These and other objects, features and advantages of the
invention will be apparent to those skilled in the art, from a
reading of the following brief description of the drawings, the
detailed description of the preferred embodiment, and the appended
claims.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The structure and the technical means adopted by the present
invention to achieve the above and other objects can be best
understood by referring to the following detailed description of
the preferred embodiments and the accompanying drawings,
wherein
[0012] FIG. 1 shows the conventional use of a resonant circuit
applied to an antenna;
[0013] FIG. 2 is an assembled perspective view of an antenna device
with an ion-implanted resonant pattern in accordance with the
preferred embodiment of the present invention;
[0014] FIG. 3 is a sectional view taken along line 3-3 of FIG.
2.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] With reference to the drawings FIGS. 2 and 3 that is an
assembled perspective view of an antenna device with an
ion-implanted resonant pattern in accordance with the preferred
embodiment of the present invention and a sectional view taken
along line 3-3 of FIG. 2, a substrate 3 of an electronic device
(not shown in the figure) includes an antenna element 4, which is
electrically connected to an antenna module (also not shown in the
figure) of the electronic device by an antenna signal feeding line
41, for transceiving a wireless signal of a predetermined radiation
frequency.
[0016] In the preferred embodiment of the present invention, the
substrate 3 could be a casing of the electronic device, and the
material of the substrate 3 could be either air, metal, or plastic
in accordance with the different fields of application of the
antenna element 4. Further, the connection between the antenna
element 4 and the antenna signal feeding line 41 could be either
direct wire connection, coupling feeding, or any other method
capable of feeding and conducting signals between the antenna
module and the antenna element 4.
[0017] In addition, the antenna element 4 is arranged on an inner
surface 31 of the substrate 3, and the wireless signal received by
the antenna element 4 from free space is conducted to the antenna
module by the antenna signal feeding line 41, while the wireless
signal generated by the antenna module is also conducted to the
antenna element 4 by the antenna signal feeding line 4.
[0018] The substrate 3 further includes an ion-implanted resonant
pattern 5 that includes a first coupling pattern 51 and a second
coupling pattern 52 arranged at a position corresponding to the
first coupling pattern with a predetermined distance d
therebetween, both of which are implanted at an adjacent position
with respect to the antenna element 4 in the substrate 3 by an
process of Ion-implantation. Moreover, the forming inside the
substrate 3 of the first and second coupling pattern 51 and 52 is
able to adapt any process other than Ion-implantation in accordance
with the application fields of the antenna element.
[0019] As the antenna element 4 transceives the wireless signal of
the predetermined radiation frequency and generates an induction
voltage V1, each of the first coupling pattern 51 and the second
coupling pattern 52 generates a coupled induction voltage and
generates a capacitance therebetween. As a consequence, the first
and second coupling pattern 51 and 52 form a resonance with the
antenna element 4, hence magnify the electrical current fed to and
transceived by the antenna element 4, so as to reduce the noise and
enhance the gain of the antenna element 4 in order to enhance the
capability of the transceiving of the wireless signal.
[0020] In the preferred embodiment of the present invention, the
forming of the ion-implanted resonant pattern 5 in the substrate 3
is by the process of Ion-implantation, which atoms or molecules are
ionized, accelerated in an electric field and implanted into the
target material (the substrate 3 in the present invention.) The
first and second coupling patterns 51 and 52, therefore, each can
be arranged at a desired position and depth in the substrate 3 or
have the desired structure and dimension in accordance the
different fields of application.
[0021] With the preferred embodiment stated above, the present
invention directly implants resonant patterns inside the structure
of an electronic device by applying the process of
Ion-implantation. Besides, the electronic device co-structured and
ion-implanted resonant pattern magnifies the electrical current fed
to and transceived by the antenna, so as reduces the noise and
enhances the gain of the antenna to upgrade the quality of the
wireless technology. Further, the present invention can be adapted
into a wide range of electronic devices when used in different
fields of application.
[0022] While the invention has been described in connection with
what is presently considered to the most practical and preferred
embodiments, it is to be understood that the invention is not to be
limited to the disclosed embodiments, but on the contrary, is
intended to cover various modifications and equivalent arrangement
included within the spirit and scope of the appended claims.
